_Treatment._ If appetite continues, diet should be restricted to a very moderate allowance of green food, pulped roots, bran mash, boiled flaxseed, boiled middlings, with pure water or whey. If there are irritants in the stomach they may be got rid of by a laxative (aloes 4 drachms, or sulphate of soda ½ pound). Sodium bicarbonate (½ drachm 2 or 3 times daily) is desirable to stimulate peptic secretion and check acid fermentations. Pepsin (2 drachms) should be given at equal intervals. Fermentations should be checked by the use of salol (1 to 2 drachms), naphthalin (1 to 2 drachms), benzo-naphthol (1 to 3 drachms), or calcium salicylate (2 drachms). In this connection bitters are of value to improve the tone of the gastric mucosa, nux vomica, gentian, quinia and quassia in combination with ipecacuan giving good results. PHLEGMONOUS (PURULENT) GASTRITIS IN THE HORSE. Definition: deep inflammation tending to abscess. Causes: invasion by pus microbes, infectious diseases, parasitism, traumas. Symptoms: hyperthermia, colic, tenderness, icterus, coincident disease, hæmatemesis. Lesions: submucous or subperitoneal abscess, parasites, peritonitis, exudation, thickening, neoplasm of mucosa, catarrhal complications. Treatment: careful diet, antiseptics, bitters, laxatives. _Definition._ This is a gastric inflammation affecting the membranous layers, and tending to submucous or subperitoneal abscess. It is much less frequent than the catarrhal form. _Causes._ It may be attributed to invasion of the gastric walls by pus microbes, and appears as secondary abscess in pyæmia and above all in strangles. The microbes are introduced more directly through the wounds inflicted by the larvæ of œstrus, or by the burrowing of these (Argus, Schlieppe, Schortmann), or of spiroptera (Argus). Wounds by sharp pointed bodies taken in with the food, furnish other infection—atria, and in their turn ulcers connected with catarrhal or toxic inflammation may furnish a means of entrance. _Symptoms._ These resemble those of catarrhal inflammation, but are usually attended by greater hyperthermia, and the colicy symptoms are more marked. There is also greater tenderness in the epigastrium and left hypochondrium, and icterus is more marked. When it occurs as an extension of strangles or pyæmia the symptoms of these affections elsewhere are pathognomonic. When the abscess bursts into the stomach there may be vomiting of bloody mucus (hæmatemesis) which is not necessarily followed by a fatal result.
